    Abstract Due to increasing global climate change problems to biota, salinity has been recognized as a realistic hazard critically affects the sustain agri-food production and crop quality in many regions of the world. Nanotechnology as an innovative approach can effectively improve plant performance under risky conditions such as salinity. Taking in consideration the ameliorative role of nanoparticles such as calcium nanoparticles (Ca-NPs) in enhancing plant growth and tolerance against various abiotic stresses, the present study was undertaken to illuminate the powerful effect and the underlying mechanism of soil-applied Ca-NPs (20 mM) in preventing salt damage at saline conditions (NaCl at 50, 100 and 200 mM) in tomato. Data revealed that NaCl drastically imposed the morphological parameters, primary and secondary metabolism, photosynthesis pigment content, hydrogen peroxide and lipid peroxidation levels, antioxidant enzyme activities, mineral contents, and protein patterns. In contrast, the supplementation of exogenous Ca-NPs modified salinity toxicity effects by improving the survival, growth parameters, anabolic (soluble ions and osmolytes) and defense mechanisms (enzymatic and nonenzymatic antioxidants). Interestingly, under lethal salinity level (200 mM), Ca-NPs was capable of suppressing the excessive damage effect of salinity by up-regulating the performance of the plants when these plants were completely dead in the absence of Ca-NPs. The descriptive cluster analysis separated treatments and characteristics into 3 to elucidate negative and positive correlations. Moreover, Ca-NPs was more efficient than CaCl₂ in eliciting salt tolerance under all investigated NaCl levels. Therefore, all these findings together conclude that Ca-NPs have a positive role in motivating resilience strategies in tomato plants toward salt stress via lessening the ROS overproduction, stimulating enzymatic antioxidants, promoting osmolytes accumulation, and renovating protein profile under mild and severe salinity levels.

    Abstract Nanoparticles (NPs) are released and dispersed in the environment because of increased manufacturing and use of nano products. NPs disturb the growth of plants depending upon types, exposure duration and plant species. The purpose of this research was to explore the role of gibberellic acid (GA) exposure through foliar route on wheat growth under alone or combined soil application of cerium oxide (CeO₂), zinc oxide (ZnO), and titanium dioxide (TiO₂) NPs. GA was foliar-applied (200 mg/L) on the wheat plants treated with individual and in all possible combination of the selected NPs. Explorations have revealed that the combination of NPs and GA worked well to enhance the plant growth and selected nutrient status than NPs alone. Furthermore, GA decreased the boosted antioxidant enzyme activities under the combination and individual NPs compared to the alone NPs treated plants, lowered the oxidative stress in wheat plants which provided the additional proof that GA decreased oxidative damage in plants. Combined NPs showed differential effects than individual NPs application irrespective of GA exposure which varied with NPs combination and studied parameters of plants. GA + NPs differentially affected the potassium, phosphorus, iron and manganese concentrations in wheat tissues than NPs alone treatments. Overall, GA can be applied when there is excess of NPs (either alone or in combination) in the growth medium to ensure the growth of crops. However, further studied are needed with other plant species and alone or combined use of different NPs under GA treatment before any final recommendation.

    Abstract Zinc oxide nanoparticles (nZn) have emerged as vital agents in combating arsenic (As) stress in plants. However, their role in mitigation of As induced oxidative stress is less studied. Therefore, this study aimed to assess the comparative role of nZn and ZnO in alleviating As toxicity in rice genotype “9311”. The results of this study revealed that nZn demonstrated superior efficacy compared to ZnO in mitigating As toxicity. This superiority can be attributed to the unique size and structure of nZn, which enhances its ability to alleviate As toxicity. Exposure to As at a concentration of 25 μM L⁻¹ led to significant reductions in shoot length, root length, shoot dry weight, and root dry weight by 39%, 51%, 30%, and 46%, respectively, while the accumulation of essential nutrients such as magnesium (Mg), potassium (K), iron (Fe), manganese (Mn), and zinc (Zn) decreased by 25%–47% compared to the control plants. Additionally, As exposure resulted in stomatal closure and structural damage to vital cellular components such as grana thylakoids (GT), starch granules (SG), and the nucleolus. However, the application of nZn at a concentration of 30 mg L⁻¹ exhibited significant alleviation of As toxicity, resulting in a reduction of As accumulation by 54% in shoots and 62% in roots of rice seedlings. Furthermore, nZn demonstrated the ability to scavenge reactive oxygen species (ROS) like hydrogen peroxide (H₂O₂) and superoxide anion (O₂.⁻), while significantly promoted the gas exchange parameters, chlorophyll content (SPAD value), fluorescence efficiency (Fv/m) and antioxidant enzyme activities under As-induced stress. These findings highlight the potential of nZn in mitigating the adverse impacts of As contamination in rice plants. However, further research is necessary to fully comprehend the underlying mechanisms responsible for the protective effects of nZn and to determine the optimal conditions for their application in real-world agricultural settings.

    Abstract Nano-enabled strategies have emerged as promising alternatives to resolve heavy metals (HMs) related harms in an eco-friendly manner. Here, we explored the potential of biogenic silicon nanoparticles (SiNPs) in alleviating cadmium (Cd) stress in rapeseed (Brassica napus L.) plants by modulating cellular oxidative repair mechanisms. Biogenic SiNPs of spherical shapes with size ranging between 14 nm and 35 nm were synthesized using rice straw extract and characterized through advanced characterization techniques. A greenhouse experiment results showed that SiNPs treatment at 250 mg kg

    Abstract Soil contamination with toxic environmental pollutants [such as cadmium (Cd)] is becoming a serious global problem due to rapid development of social economy. To improve the growth and yield of a plant, various chelating agents, such as ethylenediaminetetraacetic acid (EDTA) and citric acid (CA), can be applied to the soil; such application not only increases plant uptake of metals from the soil but also promotes plant absorption of micronutrient fertilizers from the medium. For this purpose, we have conducted a pot experiment using the exogenous application of CA (2.5 mM) and EDTA (2.5 mM) in pepper (Capsicum annuum L.) seedlings grown under the varying levels of Cd (0, 50 and 100 µM) in the soil. M]. Our results depicted that Cd addition to the soil significantly (P < 0.05) decreased plant growth and biomass, gas exchange attributes, and mineral uptake by C. annuum when compared to the plants grown without the addition of Cd. However, Cd toxicity boosted the production of reactive oxygen species (ROS) by increasing the content of malondialdehyde (MDA), which is the indication of oxidative stress in C. annuum, and was also manifested by hydrogen peroxide (H₂O₂) content and electrolyte leakage to the membrane-bound organelles. The results showed that the activities of various antioxidative enzymes, such as superoxidase dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX), and their specific gene expression and also the content of non-enzymatic antioxidants, such as phenolic, flavonoid, ascorbic acid, and anthocyanin, initially increased with an increase in the Cd concentration in the soil. The results also revealed that the levels of soluble sugar, reducing sugar, and non-reducing sugar were decreased in plants grown under elevating Cd levels, but the accumulation of the metal in the roots and shoots of C. annuum, was found to be increased. The negative impacts of Cd injury were reduced by the application of EDTA and CA, which increased plant growth and biomass, improved photosynthetic apparatus, antioxidant enzymes and their gene expression, and mineral uptake, as well as diminished the exudation of organic acids and oxidative stress indicators in C. annuum by decreasing Cd toxicity. Here, we conclude that the application of EDTA and CA under the exposure to Cd stress significantly improved plant growth and biomass, photosynthetic pigments, and gas exchange characteristics; regulated antioxidant defense system and essential nutrient uptake; and balanced organic acid exudation pattern in C. annuum.
